I've been trying for a few hours and can't get the beta wardrobe to save any of the changes I make to my avatar. ): I've had this problem before and just used the old one instead; but this time it won't work because I want to use one of the new backgrounds that you can't layer properly outside of the beta.
Do you have any browser add-ons enabled? Some of them cause problems with the beta wardrobe, you should try temporarily disabling them (or disabling them on the beta wardrobe page). I've heard that Adblock and NoScript both cause problems, though I haven't personally had any problems saving (but relayering the base layer is literally all I use the beta wardrobe for lol)
I don't have a lot of add-ons, but I tried disabling the ones I do have and still no change. ): It was working before too! It's just recently I can't get it to save at all. D;
I've been having this problem, too, and the only thing that's worked for me before was saving my avatar naked, then completely rebuilding it again.
Also having this problem right now (just trying to swap layers of two items and save), and I'm not sure what actually causes it.
I often have this issue when I'm only trying to add an item or two or alter the layering order. When I'm working on saved HAs, I also have to rebuild them from scratch in a separate tab, or else when I hit "save" it will skip saving the things that were already on.
It's a rather annoying bug, renders wardrobe slots almost useless.
I've never been able to save to a slot in the beta wardrobe :( If I use save, it just saves a naked HA with nothing on it. I have to save/load in the old wardrobe then go edit it in beta.
[edit]
I use Adblock Plus, so I just turned it off and tried to save... still doesn't work :(
I have no idea how to fix this. ; w; I tried using a computer that doesn't have any additional programs installed and nothing changed. I also tried to see if it would save my HA with other clothes or even naked and it won't do anything.
Edit:
Okay, I finally got something to save, but it kept telling me that I had too many items on certain layers when I didn't. I had to take off a lot of stuff and re-add it in the normal wardrobe.
